You need tikz 2.00 page 6 in the doc and ...

LaTeX Warning: You have requested, on input line 36, version
               `2008/01/15' of package tikz,
               but only version
               `2006/10/17 v1.10 (rcs-revision 1.68)'
               is available.

with TL2008 you have pgf/tikz 2.00. It's easy to install pgf/tikz
  manually in your texmf if you want (page 6)
